Think critically

How can the principles of safety and reliability assessment for human-rated spacecraft be adapted for the design of everyday consumer products to improve user experience and reduce accidental misuse?

05

Design Principles

"Human-centred design for critical systems demands a proactive and integrated approach to safety and reliability, informed by comprehensive analysis of human factors."

This approach moves beyond purely technical specifications to integrate human factors directly into the design process. By proactively identifying and mitigating potential human errors and ensuring systems are intuitive and manageable, designers can significantly enhance the success and safety of complex projects.

06

What This Means for Your Design

To make sure space missions with people are safe and work well, designers need to think a lot about how humans will use the spacecraft and what could go wrong, using lessons learned from past space missions and current engineering knowledge.
